*SetBeam() - arbitrary cross section
Sets the properties of a beam arbitrary cross section.
Syntax
*SetBeam(beam_name,ARBITRARY, len|AUTO_LENGTH, E,G,area, ixx,iyy,izz, asy,asz, CRATIO,ratio)
Arguments
- beam_name
- The variable name of an existing beam.
- ARBITRARY
- This argument indicates the cross section of the beam is arbitrary.
- len
- len specifies the undeformed length of the beam.
- AUTO_LENGTH
- AUTO_LENGTH indicates that the undeformed length of the beam is calculated automatically using the end points of the beam.
- E
- The Young's modulus of elasticity.
- G
- The shear modulus of elasticity.
- area
- Area of cross section of the beam.
- ixx
- Polar moment of inertia of the beam cross section.
- iyy
- Second moment of inertia of the beam cross section bout the Y axis.
- izz
- Second moment of inertia of the beam cross section about the Z axis.
- asy
- The correction factor for the shear deflection along the Y axis.
- asz
- The correction factor for the shear deflection along the Z axis.
- CRATIO
- This argument indicates the structural damping matrix is a ratio of the stiffness matrix.
- ratio
- Ratio for calculating the damping matrix.
